Gypsophila plant named ‘Pearls Petite’

ABSTRACT

A new  Gypsophila  plant particularly distinguished by having small, semi-double, white flowers and an upright shrub form type, is disclosed.

Genus and species: Gypsophila paniculata L.

Variety denomination: ‘Pearls Petite’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of Gypsophila, botanically known as Gypsophila paniculata L., and hereinafter referred to by the variety name ‘Pearls Petite’. ‘Pearls Petite’ originated from an open pollination within a group of unmarked parental lines in April 2010 in Negev, Israel.

Seeds were obtained from the open pollination and sown. Plants were then grown for evaluation. A plant line was selected in August 2010 in Negev, Israel and named ‘Pearls Petite’. In September 2010, ‘Pearls Petite’ was first vegetatively propagated in Negev, Israel by side shoot cuttings. ‘Pearls Petite’ was found to reproduce true to type in successive generations of asexual propagation via side shoot cuttings in Negrev, Israel.

SUMMARY

The following are the most outstanding and distinguishing characteristics of this new variety when grown under normal horticultural practices in Negev, Israel.

-   -   1. Small, semi-double, white flowers; and     -   2. An upright shrub form type.

DESCRIPTION OF THE PHOTOGRAPHS

This new Gypsophila plant is illustrated by the accompanying photographs. The photographs were taken in Negev, Israel as described below. The colors shown are as true as can be reasonably obtained by conventional photographic procedures.

FIG. 1 shows ten cut flowering stems of the plant in a vase from the summer of 2011.

FIG. 2 shows a plant ten-weeks from planting grown in an open field in Negev, Israel in the autumn of 2012.

DESCRIPTION OF THE NEW VARIETY

The following detailed descriptions set forth the distinctive characteristics of ‘Pearls Petite’. The data which define these characteristics were collected in Negev, Israel in the summer of 2013. Data was collected on plants ten-weeks after planting. Color references are to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.) (1986).
